Probably... well fixing endianness is the price of doing business if you're big endian. > > Why so much effort into a bad design on top of a crack transport btw ? > Is it just RH politics of there's a good reason hiding somewhere ?

I think it's prudent to wait until it's merged upstream, then we can take another look to see why ppc is so special that it can't just use it after fixing any endianness issues. -- error compiling committee.c: too many arguments to function
